Pipe Diameter Calculator allows you to calculate the diameter of any pipe using this calculator. The calculator supports two units of measurements,
SI Units and English/US Units. The calculator needs the following input to calculate the diameter:
+ Flow rate – This can be defined by selecting either Mass Flow or Volumetric Flow basis.
+ Density – Only required if using Mass Flow rate
+ Velocity in pipe.
The application has a predefined list of services the includes typical velocities that can be used for the velocity input, the purpose of this is to provide a quick estimate, you can also use your own defined velocity input if you prefer.
Below is a list of services that the application has a typical/recommended velocity range for:
Air, compressed
Gas, dry
Gas, wet
Petrochemicals
Sodium hydroxide (0 – 30%)
Sodium hydroxide (30 – 50%)
Sodium hydroxide (50 – 73%)
Steam, dry, high pressure (> 2 bar)
Steam, saturated, low pressure (
